Polastorm Polaflex propeller hub kit F13 is a replaceable hub and shock absorber kit for compatible propeller blades and outboard motors from Suzuki as well as BRP, Johnson, and Evinrude. The variant is designed for a 13-spline propeller shaft and 3 1/4" (82.6 mm) gearcases.
The hub system features an elastic rubber bushing that absorbs impact and reduces the transmission of vibrations between the propeller and propeller shaft. Power is transferred through the metal splines and the rubber bushing, which also contributes to smoother gear shifting.
The kit consists of a shock absorber/hub bushing, thrust washer, front washer, spacer, and nut. It thus contains the proven hub and mounting parts to complete a compatible propeller blade with the Polaflex F13 hub system.
F13 belongs to the C Group size category and can be used with compatible Polaris stainless steel propeller blades as well as suitable Polastorm propeller blades. Always check that the propeller blade is intended for the F13 hub system.
